Brain Tagging: A BCI and HCI Tagging System to Evaluate the Learning Contents.

In this paper, we propose a novel interactive video-based learning system, Brain Tagging. Through collecting both the passive BCI and the active HCI tagging information, the learns' objective and subjective metadata to the video contents are generated. The system gives a way to visualize the learning pattern by timeline chart consisted of BCI metadata (attention and meditation) and HCI metadata (good, question, and disagree). This can help to understand the learning process and performance, and thereby to provide proper improvement in e-learning.
